Detailed Description

The present application is described in further detail below with reference to figures 1-3.

The embodiment of the application discloses a device for reducing dust in a mixing plant. Referring to fig. 1, the device for reducing dust in the mixing plant comprises a dust remover 1, wherein the dust remover 1 is fixedly connected with a connecting pipeline 11, and the dust remover 1 is communicated with a mixing bin 2 of the mixing plant through the connecting pipeline 11. In the workstation of stirring station, can produce a large amount of dusts, the dust of production enters into dust remover 1 through connecting tube 11, and dust remover 1 gets rid of the dust, has solved the dust pollution problem of stirring station, has played the environmental protection effect.

Because the generated dust is easy to float upwards, the connecting pipeline 11 is arranged above the stirring bin 2, so that the dust remover 1 can conveniently absorb the dust.

Referring to fig. 2 and 3, although the dust collector 1 plays a role of removing dust, the problem of dust generation is not fundamentally solved, and the work load of the dust collector 1 is increased once the dust generated at the mixing station is large. For reducing the production of dust, set up buffer gear 3 in the inside in stirring storehouse 2, the inside in stirring storehouse 2 still is provided with agitating unit 4, and feed inlet 21 has been seted up to the top in stirring storehouse 2, and buffer gear 3 is located feed inlet 21 under, and is located agitating unit 4's below. Concrete raw materials get into the inside in stirring storehouse 2 from feed inlet 21, and concrete raw materials is at the whereabouts in-process, through buffer gear 3 earlier, and buffer gear 3 has played the cushioning effect to concrete raw materials to reach the effect that reduces the raise dust.

The buffer mechanism 3 comprises at least one first buffer plate 31 arranged on the inner wall of the stirring bin 2, and the first buffer plate 31 inclines towards the stirring device 4. The first buffer plate 31 plays a good role in buffering the falling concrete raw material, so that the generation of dust can be reduced.

Of course, the number of the first buffer plates 31 may be plural, thereby achieving a better buffering effect. When the first buffer plate 31 is a plurality of, the first buffer plate 31 of this embodiment is three, and three first buffer plates 31 are along the direction from the feed inlet 21 to the stirring device 4, i.e. staggered in sequence from top to bottom. The concrete raw material can play a role in reducing dust through one first buffer plate 31.

In addition, each first buffer plate 31 is provided with a plurality of second buffer plates 32 in the direction close to the feeding port 21, in this embodiment, each first buffer plate 31 is provided with three second buffer plates 32, and the second buffer plates 32 are inclined towards the stirring device 4 or perpendicular to the falling direction of the concrete material. The arrangement of the plurality of second buffer plates 32 can further reduce the descending speed of the concrete raw material, thereby playing a better buffer role.

Although the buffering effect on the concrete raw materials is further enhanced by the plurality of second buffer plates 32, water is used in the process of producing concrete, so that water vapor is easily generated in the mixing plant, the concrete raw materials and the water vapor are mixed and easily adhered to the second buffer plates 32, and the cleaning of the second buffer plates 32 is not facilitated. To solve this problem, a spring 33 is fixedly connected between the second buffer plate 32 and the first buffer plate 31, and the spring 33 is located at one end of the second buffer plate 32 close to the stirring device 4.

When the concrete raw material is dropped on the second buffer plate 32, the spring 33 is compressed due to the gravity of the concrete raw material itself, and when no concrete raw material is dropped on the second buffer plate 32 or the concrete raw material dropped on the second buffer plate 32 is reduced, the spring 33 is extended due to the disappearance or reduction of the gravity of the concrete raw material. In the workstation working process, there is the concrete raw materials whereabouts of continuous, and spring 33 also can be because the gravity of the concrete raw materials of whereabouts changes and flexible repeatedly to reach the effect of second buffer board 32 vibration, make the difficult adhesion of concrete raw materials on second buffer board 32, the vibration effect that second buffer board 32 produced more is favorable to buffering the concrete raw materials moreover, reduces the mixing plant raise dust.

In order to make the second buffer plate 32 vibrate up and down along with the extension and contraction of the spring 33, it is usually thought to hinge the second buffer plate 32 and the first buffer plate 31, but the concrete material falls into the hinge structure and is not beneficial to the use of the second buffer plate 32, so that the method of hinging the second buffer plate 32 and the first buffer plate 31 is abandoned, and the method of manufacturing the second buffer plate 32 by using an elastic material is adopted, so that the effect that the second buffer plate 32 can vibrate up and down along with the extension and contraction of the spring 33 is achieved.

Although the first buffer plate 31 and the small buffer play a role in reducing dust generation, the dust generation cannot be completely prevented, so that part of dust and water vapor are mixed and adhered to the spring 33 to influence the use of the spring 33, in order to solve the problem, a protective cloth 34 is fixedly connected between the second buffer plate 32 and the first buffer plate 31, and the spring 33 is positioned in a space formed by the second buffer plate 32, the protective cloth 34 and the first buffer plate 31. The protective cloth 34 isolates the spring 33 from dust, and protects the spring 33.

The implementation principle of the device for reducing the dust in the mixing plant in the embodiment of the application is as follows:

during the operation of the mixing plant, the concrete raw material enters from the feeding hole 21, contacts the first buffer plate 31, the second first buffer plate 31 and the third first buffer plate 31 in sequence, and finally enters the mixing device 4. When the concrete raw materials contact the second buffer board 32 on the first buffer board 31, the second buffer board 32 plays the cushioning effect to the concrete raw materials, and along with the concrete raw materials constantly falls, spring 33 is flexible repeatedly, has formed the phenomenon of second buffer board 32 vibration, has further strengthened the cushioning effect of second buffer board 32 to the concrete raw materials to better dust suppression effect has been played.

Although the first buffer plate 31 reduces the generation of dust, a small amount of dust is generated, and when a small amount of dust is generated, the spring 33 is isolated from the dust by the protective cloth 34, so that the spring 33 is protected. And a small amount of dust generated enters the dust separator 1 through the connecting pipe 11 and is removed by the dust separator 1.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
